However, in both of the ceiling panel fixing structures described in Patent Documents 1 and 2, the ceiling panel and the mounting member (the auxiliary connection member described in Patent Document 1 or the connecting member and the connecting material described in Patent Document 2) are screwed together. Since it is a structure to stop, there are the following problems. (1) Screwing requires electric tools, etc., and it takes time to install. (2) Workability is poor because the operator must reach out through an inspection opening provided in the ceiling panel of the bathroom and screw in the narrow space behind the ceiling. (3) It is necessary to secure work space for screwing work in the ceiling. (4) Pre-drilling of ceiling panels and mounting members is required. (5) Since ceiling panels and mounting members are thin, it is necessary to perform burring processing in order to secure a predetermined number of screw threads. (6) If the position of the pilot hole is misaligned, screwing cannot be done, so it is necessary to control the machining precision of the pilot hole. (7) Even if the thread is secured by burring, since the thickness of the ceiling panel and mounting members is originally thin, there is little engagement with the screw, and the thread is easily crushed, resulting in poor fixing. (8) The tightening force tends to vary depending on the operator, and excessive tightening with an electric tool may cause distortion in the ceiling panel and fixing members. (9) Once connected, it cannot be easily removed (replaced). (10) The number of parts such as mounting members and screws is large, and the number of man-hours required for mounting them is large.

A ceiling frame 8 that interconnects the middle column frames 3, 3, and the corner column frames 4, 4, is laid across the upper ends thereof. The ceiling frame 8 is a thin plate member having a cross-sectional shape with a crank portion formed in the middle in the vertical direction. It is arranged all around the panel 5 . In the ceiling frame 8, the horizontally extending portion of the crank portion provided in the middle constitutes a mounting portion 8a on which the peripheral portion of the ceiling panel 5 is mounted, and the outer edge of the mounting portion 8a. The portion rising from the ceiling panel 5 constitutes an upper support portion 9 facing the peripheral rising piece portion 7 of the ceiling panel 5, and the portion hanging down from the inner edge of the mounting portion 8a is a fixing portion for the column frames 3 and 4 and a fixing portion to be described later. A lower support portion 8b that also serves as an engaging portion for the lower end engaging portion 15 of the fixed clip 10 is formed. As shown in FIG. 3, the ceiling frame 8 is bent at approximately 90 degrees along the inner and upper end surfaces of the column frames 3 and 4 at the positions where the column frames 3 and 4 are arranged. , and are bent at approximately 90 degrees so as to stand upward at the rear side positions of the column frames 3 and 4 .

In the fixing structure according to the present invention, the ceiling frame 8 and the ceiling panel 5 are connected by fixing clips 10, as shown in FIG. As shown in FIGS. 4 and 5, the fixing clip 10 is configured such that the peripheral upright piece portion 7 of the ceiling panel 5 and the upper support portion 9 of the ceiling frame 8 are positioned between the opposing wall surfaces 11 and 12 from below.

Thus, in the fixing structure according to the present invention, since the ceiling panel 5 can be easily fixed by the fixing clips 10, it has the following merits as compared with the conventional fixing structure using screws.
(1) Conventional screw fastening work required electric tools and took time to install, but this fixing structure can be installed with a single touch, shortening the installation time.
(2) In the conventional screwing work, workability was poor because it was necessary to reach out from the ceiling inspection opening and screw in the space behind the ceiling. It is easy to install by reaching out from the inside to the edge of the ceiling, so workability is good.
(3) In the conventional screwing work, it was necessary to secure work space behind the ceiling when screwing. No need to reserve work space.
(4) In the conventional screwing work, each member had to be drilled with a pre-drilled hole for screwing.
(5) In the conventional screw fastening work, burring processing was required before drilling a pilot hole.
(6) In the conventional screwing work, it was impossible to install if the pilot holes for screwing between each member were misaligned. Installation failure due to misalignment does not occur.
(7) In the conventional screwing work, since the thickness of each member is thin, the screw threads are easily crushed and installation failures are likely to occur. No defects occur.
(8) In the conventional screw fastening work, there were variations in the tightening force depending on the operator, and there was a risk that the ceiling panel and fixing members would be distorted due to over-tightening with electric tools. There is no variation among operators, and the quality of assembly is good and stable.
(9) With the conventional screw fixing work, once connected, it could not be easily removed (exchanged), but with this fixing structure, it is also easy to remove after connecting.
(10) In the conventional screwing work, there are many parts such as connecting members and screws (the structure described in Patent Document 1 has one connection auxiliary member and two screws, and the structure described in Patent Document 2 has a connecting 2 points (member and connecting material, 1 screw), and the number of man-hours to install them was increased. Less man-hours.

To explain the fixing clip 10 in more detail, the fixing clip 10 is a mold-molded product made of resin. By being suspended, the holding portion 13 is formed by the space between the wall surfaces 11 and 12, the wall surface 12 on the rear surface side extends relatively downward from the wall surface 11 on the front surface side, and The front end thereof is bent toward the front side, and the lower end engaging portion 15 is provided at the front end of the bent portion 12a.

The gap width of the holding portion 13 (separation width between both wall surfaces 11 and 12) is a dimension that allows insertion of the upper support portion 9 of the ceiling frame 8 and the peripheral upright piece portion 7 of the ceiling panel 5 in a state of being overlapped. formed. The holding portion 13 is provided over the entire width of both wall surfaces 11 and 12 and is formed so as to penetrate both side surfaces of the fixing clip 10 .
